Abstract.Th e article provides a closer look into the quality properties of fuels, analyses the merits and demerits of using biocomponents in petrol and diesel and overviews the ways of improving the quality of fuels. Work carried out by the authors covers the determination of the basic quality properties (density, kinematic viscosity and fl ash point) of petrol, diesel, methanol, ethanol, buthanol as well as rape methyl and rape ethyl esters. Th e paper investigates how these qualities infl uence the operational performance of the engine and puts forward the age-dependence analysis of diesel quality properties.

“…For the comparison of emissions, CO emissions resulting from the use of hydrous ethanol was less than that of gasohol by 41%, the reason behind its water present during combustion might act to decrease CO emissions by way of the water-gas shift mechanism, it also found that the HC produced from the use of hydrous ethanol was higher than that of gasohol by 56%. Trends in HC emissions are highly variable since it depends on charge heterogeneity [83], combustion chamber design [10], flame quenching [84] and other engine related parameters. However, hydrocarbon emissions would increase when the mixtures were down beyond the lean limit [74].…”

This paper reviews the serviceability of hydrous ethanol as a clean, cheap and green renewable substitute fuel for spark ignition engines and discusses the comparative chemical and physical properties of hydrous ethanol and gasoline fuels. The significant differences in the properties of hydrous ethanol and gasoline fuels are sufficient to create a significant change during the combustion phase of engine operation and consequently affect the performance of spark-ignition (SI) engines. The stability of ethanol-gasoline-water blends is also discussed. Furthermore, the effects of hydrous ethanol, and its blends with gasoline fuel on SI engine combustion characteristics, cycle-to-cycle variations, engine performance parameters, and emission characteristics have been highlighted. Higher water solubility in ethanol-gasoline blends may be obviously useful and suitable; nevertheless, the continuous ability of water to remain soluble in the blend is significantly affected by temperature. Nearly all published engine experimental results showed a significant improvement in combustion characteristics and enhanced engine performance for the use of hydrous ethanol as fuel. Moreover, carbon monoxide and oxides of nitrogen emissions were also significantly decreased. It is also worth pointing out that unburned hydrocarbon and carbon dioxide emissions were also reduced for the use of hydrous ethanol. However, unregulated emissions such as acetaldehyde and formaldehyde were significantly increased.

The use of renewable fuels is pointed out as one of the best solutions to decrease the greenhouse gases emissions due to the balance in the CO2 chain. In this context, ethanol stands out as one of the best renewable fuels. Furthermore, the direct use of hydrated mixtures of this fuel can improve the energy balance, reducing the fuel cost. The increase in water concentration leads to lower indicated efficiencies. However, the water promotes an increase on knock resistance. This enables the use of higher compression ratios, improving the engine conversion efficiency. The modifications in this parameter to use wet ethanol mixtures is not well established. In this way, this study, aims to evaluate the impact of compression ratio increase on heat release and performance parameters. Mixtures containing 4, 10, 20 and 30% of water in ethanol in volumetric content were investigated. The tests were carried out at 8 bar BMEP and 1800 rpm. As a result, the increase in water concentration allowed operation at minimum spark advance for best torque (MBT) for compression ratios up to 14.5. INTRODUÇÃOUm dos grandes desafios da indústria automobilística é desenvolver seus motores para atingir os níveis de emissões regulamentados, principalmente dos gases que intensificam o efeito estufa. Para isso, o desenvolvimento de combustíveis que produzam menos emissões de CO2 do que os combustíveis fósseis são indispensáveis. Visando atender às regulamentações apresentadas na Conferência de Mudanças Climáticas das Nações Unidas em 2015 [1], muitos estudos vem sendo focados na pesquisa e desenvolvimento de combustíveis sustentáveis. Tais combustíveis devem apresentar baixa emissão de gases do efeito estufa, serem renováveis e economicamente rentáveis para se produzir.Neste cenário, o etanol surge como um dos melhores combustíveis alternativos, com propriedades fisico-químicas interessantes para a combustão. O etanol possui ainda um grande potencial de produção, sendo obtido das mais diversas culturas, criando empregos e renda, especialmente para países emergentes [2]. Não obstante, ainda é necessário obter processos de produção mais baratos e obter subsídio do governo de forma a tornar este combustível tão viável quanto combustíveis como o diesel ou a gasolina.
